Description
Technical field
It the utility model is related to Material Field, more particularly to a kind of composite membrane.
Background technology
At present, heat-barrier material composite membrane, several tunics are typically carried out to compound, such as use using two-component glue
4050A and 4050B two-component glue.Usual this film has the disadvantages that, such as：Cost is high, delivery date is long, cumbersome.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of non-aging, not fugitive layer
Composite membrane.
The purpose of this utility model adopts the following technical scheme that realization：
A kind of composite membrane, include PET basic units, the first adhesive layer, aluminium foil layer, the second adhesive layer and high score successively from top to bottom
Sub- film layer, first adhesive layer and the second adhesive layer form by polyurethane binder coating；The macromolecule membranous layer is to change
Property PE grafted maleic anhydrides.
Preferably, the thickness of the PET basic units is 0.025-0.05mm.
Preferably, the carrying capacity of first adhesive layer is 3.0-6.0g/m2。
Preferably, the thickness of the aluminium foil layer is 0.007-0.015mm.
Preferably, the carrying capacity of second adhesive layer is 3.0-6.0g/m2。
Preferably, the thickness of the macromolecule membranous layer is 0.035-0.06mm.
Preferably, the thickness of the PET basic units is 0.02-0.04mm, the carrying capacity of first adhesive layer is 4-5g/
m2, the aluminium foil layer thickness be 0.009-0.011mm, the carrying capacity of the second adhesive layer be 4-5g/m2, the macromolecule membranous layer
Thickness is 0.04-0.05mm.
Compared with prior art, the beneficial effects of the utility model are：
Composite membrane provided by the utility model, because using viscoelastic polyurethane between PET basic units, aluminium foil layer and macromolecule membranous layer
Mixture is bonded, and combined strength bination is big, is not easy to scatter, not fugitive layer.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure, each reference：1st, PET basic units；2nd, the first adhesive layer；3rd, aluminium foil layer；4th, the second adhesive layer；5th, macromolecule
Film layer.
Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further, it is necessary to explanation is,
On the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
In detailed description below, described " on ", " under " etc. carries the word of temporald eixis, it is understood that to attached
The temporald eixis of figure, and should not be construed the orientation restriction to actual product.
The utility model provides a kind of composite membrane, as shown in figure 1, it is gluing to include PET basic units 1, first successively from top to bottom
Layer 2, aluminium foil layer 3, the second adhesive layer 4 and macromolecule membranous layer 5, first adhesive layer and the second adhesive layer are by polyurethane sticking
Agent coating forms；The macromolecule membranous layer is modified PE grafted maleic anhydride.
In the composite membrane, the first adhesive layer is to be coated on by polyurethane binder in PET basic units, by way of thermal-adhering
Carry out compound with aluminium foil layer and obtain, the carrying capacity of first adhesive layer is 3.0-6.0g/m2.And the second adhesive layer is by polyurethane
Adhesive is coated on aluminium foil layer surface, then at macromolecule membranous layer by thermal-adhering it is compound and, the carrying capacity of the second adhesive layer is
3.0-6.0g/m2。
In the composite membrane, the PET basic units are preferably that two layers of PET is combined by polymethyl methacrylate viscose glue.PET
The thickness of basic unit is 0.025-0.05mm.
In the composite membrane, the thickness of the aluminium foil layer is 0.007-0.015mm.Aluminium foil layer rises preferably in the composite membrane
Transmission effect that is heat-insulated and slowing down heat, effectively reduce the pyrocondensation caused by too fast heating of PET basic units or macromolecule membranous layer and deform
The problems such as, make the composite membrane that there is preferable heat resistance.
In the composite membrane, the thickness of the macromolecule membranous layer is 0.035-0.06mm.
In the utility model, each layer is more as follows than more preferably thickness matching relationship：The thickness of the PET basic units is
0.02-0.04mm, the carrying capacity of first adhesive layer are 4-5g/m2, the aluminium foil layer thickness be 0.009-0.011mm, the
The carrying capacity of two adhesive layers is 4-5g/m2, the thickness of the macromolecule membranous layer is 0.04-0.05mm.It is compound under the thickness relationship
Film, on the basis of with preferable thermal resistance performance, it can also keep preferable anti-deformation behavior.
Above-mentioned embodiment is only preferred embodiment of the present utility model, it is impossible to is protected with this to limit the utility model
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model scope claimed.
